Join some presenters (5)
I believe the answer is:
enter
'join' is the definition.
(I've seen this in other clues)
'some presenters' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ENTER' is hidden within 'presenters'.
(Other definitions for enter that I've seen before include "Set foot in" , "Go in and put in the ledger" , "Pierce" , "Come or go in" , "Introduce" .)
